RESUMO

The dynamics of hydrochemical and hydrobiological conditions in the Kodyma River, a tributary of the Bug River, were analyzed during the period from 1973 to 1991, i.e., before, during, and after land reclamation in the river valley. The results show that the consequences of stress load on the biota and the sharp impairment of ecological conditions, which were observed at the peak of works, are being gradually compensated owing to natural processes, such as secondary paludification of the river valley and restoration of its meandering course. Both biotic and abiotic indices gradually return to the initial values, although the recovery of biocenoses is far from being complete.
